  • Patent number: 7074640
    Abstract: The present invention involves a low-temperature, photoresist-free method of fabricating a barrier layer on a flexible substrate. An embodiment involves the conversion of a precursor into a top-surface imaging layer during a direct patterning step. Preferred precursors are formed from a metal complex comprising at least one ligand selected from the group consisting of acac, carboxylato, alkoxy, azide, carbonyl, nitrato, amine, halide, nitro, and mixtures thereof and at least one metal selected from the group consisting of Li, Al, Si, Ti, V, Cr, Mn, Fe, Ni, Co, Cu, Zn, Sr, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, In, Sn, Ba, La, Pr, Sm, Eu, Hf, Ta, W, Re, Os, Ir, Pt, Au, Pb, Th, U, Sb, As, Ce, Mg, and mixtures thereof.

  • Patent number: 7033942
    Abstract: A composition for chemical mechanical polishing includes a slurry. A sufficient amount of a selectively oxidizing and reducing compound is provided in the composition to produce a differential removal of a metal and a dielectric material. A pH adjusting compound adjusts the pH of the composition to provide a pH that makes the selectively oxidizing and reducing compound provide the differential removal of the metal and the dielectric material. A composition for chemical mechanical polishing is improved by including an effective amount for chemical mechanical polishing of a hydroxylamine compound, ammonium persulfate, a compound which is an indirect source of hydrogen peroxide, a peracetic acid or periodic acid. A method for chemical mechanical polishing comprises applying a slurry to a metal and dielectric material surface to produce mechanical removal of the metal and the dielectric material.

  • Publication number: 20040180292
    Abstract: The present invention relates generally to a method and apparatus for converting a precursor material, preferably organometallic, to a film, preferably metal-containing, that is adherent to at least a portion of a substrate. Both method and apparatus include a pre-conversion step or section, and a step or section for substantial conversion of a portion of material from the pre-conversion step or section into the form of a predetermined pattern, wherein this substantial conversion results in a metal-containing patterned layer on the substrate.

  • Publication number: 20020134963
    Abstract: A new cleaning chemistry based on a choline compound, such as choline hydroxide, is provided in order to address the problem of dual damascene fabrication. An etch stop inorganic layer at the bottom of a dual damascene structure protects the underlying interconnect of copper and allows a better cleaning. A two step etch process utilizing the etch stop layer is used to achieve the requirements of ULSI manufacturing in a dual damascene structure.
